SECTIONAL STAND.

Specification of Letters Patent.

Patented Feb.v I6, 1909.

Application filed March 13, 1908. Serial No. 420,787.

T all whom it may concern:

Be it known that I, FRANK G. GBIMLER, a

citizen of the United States, and a resident sccihled relation; also inimprovements in .in species of the units themselves, to- U with meansfor dotuchubly holding the lump socket at the upper end of the stand.

Reference is to he had to the accompanying drcwin s forming a part ofthis specification, in which similar characters of reference-indicatecorresponding parts in all the views. 7

' Figure l is a side elevation of a stand embodyingnry improvements;Fig, 2 it central vertical ection oi the some onun enlarged sonic; Fig.3 is a cross-section on tholine of 2; Fig. i is plan of one or the unitsof which the stand is composed Fig. 5 is a. central sectional viewthrough the lower portion of a slightly modified fi'illll of stand 6 isa perspective view oi a modified form unit; Fig. fro-glue:lturyscctionsl view through ester-11d made up of the units wn Fig. 1 Fig. 8is it view partly in vertical section, showing; a modification of themeans for holding the lump; Fig. 9 is a vertical section oi the holdershown. in 8, taken at substantially right angles thereto; and Fi 10 is aview partly in section, showing a. modified form of holder.

Referring more particularly to the -forin of the invention shown Figs. 1to at inclusive, it will he sec-n that the stand cornprises a base 10,preferably constructed of sheet or cast metal of ornamental form,

fixed unit 11, a series of units 12, relatively shorter than the unit11, and conductors 13, passing through the base and several units,having connections operating to retain the several units in assembledrelation. effected by providing the conductors with a casing 14,preferably of wire spirally Wrapped, which is secured at opposite-endsThis is to conical plugs 15, said plugs respectively seating in a.counterpart recess formed in the upper end of the top unit and the lowerend of u tubular guide member 16, the latter having the lower portionthereof threaded and is slidublc in an enlarged or counterborcd portion17 providml in the lower end of the fixed unit ll. The tube 16 is heldagainst rotation by providing gibs at opposite sides, preferably at itsup icr end, formed by bondin; the metal outwardly from the body of thetube, as indicated at 18, whichgibs slide in ways 19, iormed in thecounterbore o'i'the unit ll. On the thrcnded portion oi the guide tube16 are :r nut 20, a washer 21,.ond a spring 22 erreneed between thewasher sndthe unit 1], this construction obviously providing for theadjustment of the tension on the flexible casing 14 of the conductors,whereby the force. with which the several units are pressed together,and consequently the stiilncss of the stand, may be varied.

The units 12 have concave and convex opposits ends, as in theconstruction disclosed in my potent ubovc i'c-" erred to, but are,however, modified to the extent of forming; their central apertures ofuniform taper instead of elder-gin these apertures in the upper portionof each unit only. In attaching the lump in this form of my invention l.have shown atube 23 which fits over and is secured to the top unit 12,the lamp socket being received and held in the outer end of this tube.

The construction illustrated in Fig. 5 is in 1 all respects the some asthat just described, except at the lower portion 01 the stand, where,instead oi'- supporting the unit ll on s. sheet metal base, the latteris replaced lay su .i iortin le s 24 and a casin 25 telescopconstructed,two adjacent units will move as" though rigidly connected together, whenthe stand isbent ino'ne direction, and when the i ture at one end ofeach unit only in th direction in which the next adjacent unit turns,

claim as new and Patent:

stand is bent in the opposite direction the This wire-holder ispreferably constructed of one piece of wire by bending the wire uponitself intermediate its length, and providing the looped or doubleportion with a U-shaped member 26, of such size to bind within the tube,and then forming opposed laterally curved loops in the free ends of thewire and joining the extremities thereof, as illustrated in Fig. 8, thusproducing the jaws of the holder. If desired, the conductors may be runto the lamp at the outside of the tube by moving the clamping jaws asufficient distance above the top edge-of the tube.

In Fig. 10 I have shown the wire holder secured within a threadedthimble 23 which replaces the tube 23 and is designed to be threadeddirectly into a socket.

Having thus described my invention, I

1. A sectional stand composed of a. series of units, certain of saidunits having curved faces contacting with counterpart faces of the nextadjacent units, and the direction of curvature of the faces-of the sameunit being different.

2. A sectional stand composed of a series of units 'movable one upon theother, certain ofsaid units having curved contacting faces, with thedirection of curvature of one face arranged at substantiallyright-angles to the direction of curvature of the other face.

3. A holder having oppositely-disposed clamping jaws for embracing alamp socket,

and a U-shap'ed shank adapted to frictionally engage within a tube.

4. A holder constructed of a single piece of wire bent upon itselfintermediate its length and into U-shape for engaging within a tube, andwith the free ends of the wire desire to secure by Letters tube, havingconical plugs attached to its bent to form oppositely-disposed clampingjaws for embracing the socket of a lamp.

5. A sectional stand composed of a series of units relatively movableone upon the other and each having an aperture, a flexible memberpassing through the apertures of the units, having means for engagingthe stand at one end, a guide tube surrounding and held on the member atthe opposite end and having a threaded portion, a nut on the threadedportion of the guide tube, and a spring interposed between the stand andnut.

6. A sectional stand composed of a series of units relatively movableone upon the other, each having an aperture, a flexible member passingthrough the apertures of the units, a guide tube, pin s secured to theopposite ends of said member, respectively engaging the stand and theguide tube, a nut threaded on the guide tube, and a spring interposedbetween the stand and nut.

7. A sectional standc composed of a series of units relatively movableone upon the other and each having an aperture, and the bottom unitprovided with a counterbored portion on its under side, a guide tubeslidable in the counterbored portion of the bottom unit, having a gibprojecting from the side thereof engaged in a way in the bottom unit, aflexible member passing through the apertures of the units and throughthe guide opposite ends respectively engaging with the nut threaded onthe tube, and a spring interposed between the nut and the bottom unit ofthe stand. 1

8. The combination of a stand for carrying a lamp, a tube telescopingover the upper end of thestand, and a wire holder having a substantiallyU -shaped shank, engaging within the tube, and provided with opposedclamping jaws adapted to embrace the lamp.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
